Abstract: The strip curtain has a plurality of glide elements which are guided by a curtain rod and connected with each other by separation-limiting devices. The free hanging curtain strips are suspended from vertical pivot axes with limited excursion. Operation of the pivot axis is by a pinion which engages a bead chain that is slidably guided by the curtain rod. The pinion is connected to the pivot axis by a worm drive, a slip coupling being provided between the pinion and the worm drive. The bead chain serves as common drive for producing pivotal movement and sliding movement of the curtain strips. The strip curtain is of simple construction and therefore reliable in operation and inexpensive and suitable for mass production.

Said automatic drive unit is provided with a torque limiting device. Moreover, a timing device is connected to said drive unit for all blinds in the group for automatic actuation of all said drive units at determined points of time and setting of the slats in all blinds to closed or open position irrespective of their existing position set by said hand-operated mechanism.

Abstract: A frame for stretching artists' canvases comprises hollow sections (1, 2), in the recesses of which are inserted an insert (3, 3') that forms an angle at the corners. Each insert has a notch (4, 4') in which the bent end of a square spring (5, 5') fits. The spring is solid at the other end with a block (6, 6') that can slide in a guide (1', 2') and is provided with a tension screw (7, 7'). By the screw being tightened, the sections (1, 2) are thrust outward, leaving a space (10) between them, and causing the stretching of the canvas.

Abstract: A unitary dual track for retaining drapery panels each suspended from movable apertured lugs in the tracks. The tracks are offset so as to provide a clearance space which permits fasteners to be inserted through a top wall common to the tracks into a ceiling for mounting thereof, and shield means to bridge said space. An integrally formed master carrier member is slidably retained in each track which includes a plurality of depending lugs each having an aperture for receipt therein of hooks secured to the lead portion of a drapery panel, and a wand for moving the master carrier and the drape panel attached thereto with reduced stress on the lead portions of the drapery panels.

Abstract: A pleat screen includes a screen sheet having a plurality of zig-zag pleats and vertically foldable and unfoldable by an operator cord. At least one tape extends vertically through the pleats. Holders are mounted on the tape in engagement with selected ones of the pleats for supporting, from below, the selected pleats to prevent the pleats from being lowered due to their own weight when the screen sheet is vertically unfolded.

Abstract: A blind assembly of the type supported within a window frame of a camper, van or similar vehicle, is provided to provide quick installation and removal as well as positional stability once the assembly is in place. The blinds which obscure or block the passage of light include a plurality of strips 12 supported in parallel fashion by strings 14 extending between top and bottom header beams 16.

Abstract: A Venetian blind has U-shaped mounting rail with lead-in holes for ladder-tapes, cords and slat operating means. The Venetian blind comprises an operating shaft and bearing blocks, bearing bushings, hold-down means, a driving device therefor, and a cord lock. These details are designed as snap-in components adapted to be mounted in said mounting rail without necessitating the use of any special mounting means. The operating shaft is non-rotatable relative to and extends through the bearing bushings and is locked against axial displacement, on the one hand by means of an abutment face provided on said hold-down means at one shaft end and, on the other hand, by means of the shaft driving device at the other end of the shaft.

Abstract: A lightweight frame for stretching or blocking fabric material comprising elongated metal side frame elements detachably coupled together at their adjacent ends by a coacting pair of corner elements which are selectively expandably movable and contractibly movable relative to one another, so as to increase or decrease the frame size. Rotatable actuators coacting with the corner elements provide for the selective expansion and contraction of the corner elements relative to one another, to thereby cause said expansion and contraction of the frame. By providing a series of different lengths of side frame elements, substantially different frame sizes can be expeditiously provided. The paired corner elements and the coacting side frame elements have means thereon for rapidly detachably coupling the frame and corner elements together, as well as for rapidly securing fabric material to and removing fabric material from the frame proper.
